CAPSU LE-BOTTLE TOP.

SPECIFICATION forming part of Letters Patent No. 661,836, dated November13, 1900.

Application filed April 12, 1900.

To (I/ZZ whom, it may concern:

Be it known that I, FRANK A. WILMoT,a citizen of the United States,residing at Bridgeport, county of Fairfield, State of Connectiout, haveinvented a new and useful Capsule- Bottle Top, of which the following isa specification.

My invention relates to a class of bottles which I term for conveniencecapsule-bottles-that is, bottles used for aerating beverages by means ofsparklets or capsules charged with carbon dioxid or other gas; and myinvention has for its object to provide a bottle-top-that is, themetallic cover which is rigidly secured to the neck of the bottle and isprovided with means for holding the capsule securely while the cap isperforated and the gas let out and which also holds the gas so that itcannot escape and the water or other beverage contained in the bottlemust become charged therewithwhich shall be made entirely from sheetmetal and the parts of which shall be made wholly'by presswork and bysimple and inexpensive operations and shall be so constructed that theymay be assembled and secured together in a manner that will securedurability and a degree of strength far in excess of the greatestpossible requirements and at a minimum expense.

With these ends in view I have devised the novel capsulebottle top whichI will now describe, referring to the accompanying drawings, formingpart of this specification, and using reference characters to designatethe several parts.

Figure 1 is an elevation of my novel bottletop detached, and Fig. 2 is acentral vertical section thereof.

A denotes the gas-chamber, which isusually approximately spherical inshape and is made of two pieces of sheet metal secured together by ajoint 10. Below the gas-chamber is a neck 13, and below the neck is abase G, which is adapted for attachment, ordinarily by screw-threads,toa bottle-neck. (Not shown in the drawings.) My invention lies in theconstruction of the base and in the attachment of the gas-chamber to thebase at the neck. The metallic parts below the gas-chamber are SerialNo. 12,598. illo model.)

three in numberviz., the outer shell 61 of the base, the inner shell 9of the base, and the locking-tube f. The upper edge of shell (1 abutsagainst the lower edge of the gaschamber at the neck, the joint beingindito engage a corresponding screw-thread (not shown) on thebottle-neck. It will of course be understood that the special contour-i.6.,

the design-ofeither the gas-chamber, the

neck, or the base is not of the essence of my invention, but may beVaried to any extent without departing from the principle of myinvention. The inner shell in practice follows the contour of the outershell, excepting, of course, that the inner shell is threaded and isprovided at its upper end with a downwardlyturned flange 15, whereby apocket 16 is formed to receive a gasket or other packing 17. Thelocking-tube f is shown as extending through the neck and upward intothe gas-chamber and downward parallel with flange 15. The upper end ofthe lockingtube is upset-7I. 6., flared outward above 'joint 11, as at18-so as to form a tight joint with the wall of the gas-chamber, and isagain upset or flared outward below joint 11, as at 19, so as to form atight joint with the upper end of the base. The neck is preferably aconcave curve, as shown in the drawings, and the locking-tube betweenupset portions l8 and 19 is caused to conform closely to the 1 curvatureof the neck, so as to make a tight joint between the parts. Below upsetportion 19 of the tube is a straight portion 20,

which lies closely in engagement with down-- comprising a gas-chamberand a base, said base consisting of inner and outer shells and and belowtheirpoint of intersection.

2. A bottle-top of the character described comprising a gaschamber and abase, said base consisting of an outer shell having a flange 12 and aninner shell whose lower end is curved about said flange whereby a bead13 is formed, the base and gas-chamber being secured together by alocking-tube which is upsetabove and below their point of intersection.v 1

3. A bottle-top of the character described comprising a gas-chamber anda base, said base consisting of an outer shell having a flange 12 and aninner shell-whose lower end iscurved about said flange whereby a bead 13is formed and whose upper end is provided witha flange 15, the base andgas-chamber being secured together by a locking-tube which is upsetabove and below their. point of intersection and lies in contact withflange l5.

4. A bottle-top of the character described comprising a gas-chamber anda base, said base consisting of an outer shell and an in ner shellsecured together at their lower ends by a bead, the upper end of saidinner shell having a downwardly-turned flange whereby a pocket 16 isformed and the base and gaschamber being secured together by alockingtube which is upset above and below their point of intersectionand whose lower end lies in contact with the flange upon the inner tube.

5. A bottle-top of the character described comprising a gas-chamber, aneck and a base, said base consisting of inner and outer shells and saidneck consisting of the abutting ends of the gas=chamber and the outershell and a locking-tube lying within said abutting ends and upset bothabove and below their point of intersection.

In testimony whereof I affix my signature in presence of two witnesses.
